The concept of paradigms in the structure of scientific revolutions by thomas kuhn

In wide scientific, religious or other epistemological context, the term paradigm can indicate the concept of formal organization scheme, and be used as a synonym for frame theory or set of theories. This concept was originally specific grammar; in the Merriam-Webster Dictionary defined its use only in such a context, or in rhetoric to refer to a parable or a fable.

InKuhn added a postscript to the book in which he replied to critical responses to the first edition. About motion, in particular, his writings seemed to me full of egregious errors, both of logic and of observation. Ludwik Fleck developed the first system of the sociology of scientific knowledge in his book The Genesis and Development of a Scientific Fact He claimed that the exchange of ideas led to the establishment of a thought collective, which, when developed sufficiently, served to separate the field into esoteric professional and exoteric laymen circles.

Harvard University had denied his tenure, a few years before. However, by the mids, his book had achieved blockbuster status. Kuhn also addresses verificationisma philosophical movement that emerged in the s among logical positivists.

The verifiability principle claims that meaningful statements must be supported by empirical evidence or logical requirements.

What types of lexicons and terminology were known and employed during certain epochs? Kuhn did not see scientific theory as proceeding linearly from an objective, unbiased accumulation of all available data, but rather as paradigm-driven.

Rather, they are concrete indices to the content of more elementary perceptions, and as such they are selected for the close scrutiny of normal research only because they promise opportunity for the fruitful elaboration of an accepted paradigm.

Far more clearly than the immediate experience from which they in part derive, operations and measurements are paradigm-determined. Science does not deal in all possible laboratory manipulations.

Instead, it selects those relevant to the juxtaposition of a paradigm with the immediate experience that that paradigm has partially determined. As a result, scientists with different paradigms engage in different concrete laboratory manipulations.

For instance, eighteenth century scientists believed that homogenous solutions were chemical compounds. Therefore, a combination of water and alcohol was generally classified as a compound. Nowadays it is considered to be a solution, but there was no reason then to suspect that it was not a compound.

Water and alcohol would not separate spontaneously, nor will they separate completely upon distillation they form an azeotrope. Water and alcohol can be combined in any proportion.

Under this paradigm, scientists believed that chemical reactions such as the combination of water and alcohol did not necessarily occur in fixed proportion.

Under this new paradigm, any reaction which did not occur in fixed proportion could not be a chemical process. Copernican Revolution A famous example of a revolution in scientific thought is the Copernican Revolution. As accuracy of celestial observations increased, complexity of the Ptolemaic cyclical and epicyclical mechanisms had to increase to maintain the calculated planetary positions close to the observed positions.

Copernicus proposed a cosmology in which the Sun was at the center and the Earth was one of the planets revolving around it. For modeling the planetary motions, Copernicus used the tools he was familiar with, namely the cycles and epicycles of the Ptolemaic toolbox.

Kuhn illustrates how a paradigm shift later became possible when Galileo Galilei introduced his new ideas concerning motion. Intuitively, when an object is set in motion, it soon comes to a halt. A well-made cart may travel a long distance before it stops, but unless something keeps pushing it, it will eventually stop moving.

Chapter II - The Route to Normal Science.

Aristotle had argued that this was presumably a fundamental property of nature: Given the knowledge available at the time, this represented sensible, reasonable thinking. Galileo put forward a bold alternative conjecture: Galileo had no equipment with which to objectively confirm his conjecture, but he suggested that without any friction to slow down an object in motion, its inherent tendency is to maintain its speed without the application of any additional force.Thomas Kuhn's Structure of Scientific Revolutions (SSR) is believed to be one of the most important books in the 20th century.

The book conceived a whole industry of . Thomas Kuhn - The Structure of Scientific Revolutions It has been the case for centuries that new theories have been developed which explain more things with less assumptions, and thus help to remove some of the earlier paradoxes and the proliferation of ad hoc solutions to emerging problems.

The Structure of Scientific Revolutions by Thomas S. Kuhn Outline and Study Guide Kuhn describes how paradigms are created and what they contribute to scientific (disciplined) inquiry. facts (constructs/concepts) that the paradigm has shown to be particularly revealing of the nature of things (25).

2. Matching of facts with theory. These two aspects are intimately related, and the key concept that Kuhn develops is that of "paradigm" -- a reigning or dominant approach to solving problems in a given area of science.

Kuhn presented his views in Structure of Scientific Revolutions (first edition , second edition ). Fifty years ago, a book by Thomas Kuhn altered the way we look at the philosophy behind science, as well as introducing the much abused phrase 'paradigm shift' Kuhn's version of how science.

The Kuhn Cycle is a simple cycle of progress described by Thomas Kuhn in in his seminal work The Structure of Scientific Revolutions. In Structure Kuhn challenged the world's current conception of science, which was that it was a steady progression of the accumulation of new ideas.
